摘要： According to one embodiment, a laminate includes a first active material-containing layer, a first film and a second film. The first film includes an inorganic material, and a back surface thereof is in contact with a front surface of the first active material-containing layer. The second film includes organic fibers, and one of front and back surfaces is in contact with a front surface of the first film. An absolute value of a difference between surface roughness Ra1 of the front surface of the first active material-containing layer and surface roughness Ra2 of the back surface of the first film is 0.6 μm or less (including 0).

摘要： According to one embodiment, a silicon-containing product forming apparatus includes a reaction chamber, an emission path, a process liquid tank, a supplier, and a flow path switcher. The emission path emits an emission material from the reaction chamber. The supplier includes a supply line configured to supply a process liquid to the emission path from the process liquid tank, and a byproduct generated by reaction is treated in the emission path by the supplied process liquid. The flow path switcher switches the communication state of the emission path with each of the reaction chamber and the supply line of the supplier.
